An earlier picture with this interactive feature was published in error. It showed anti-Trump protesters in Budapest on Jan. 20; it was not from the women’s march the following day, Jan. 21. Another earlier picture, from Pittsburgh, showed a feminist rally in a different part of the city from the main women’s march. And the credit for the picture from Buffalo misstated the photographer’s affiliation. It is not the case that the photographer, Mary Lane Scherer, works for The New York Times.
